Non-Major (Air Pollutant) Source Construction and Operation Permit Applications – AQD Forms

Friday, June 5, 2015

Minor sources of air pollution are those that have the potential to emit air pollutants at rates below defined major source thresholds. These sources generally require a Chapter 2 [PDF] pre-construction review permit prior to commencement of construction and a Chapter 2 [PDF] operating permit following completion of construction. In the District, minor sources include gas stations, dry cleaners, auto body shops, sites using generators, and small printing facilities.
